the following-is a specification.

Bronze varnishes of good quality must have no ingredients, which change the brightness of the highly fine and sensitive bronze powder to a dull varnish.

Processes, as hitherto known, of manu facturmg bronze varmshes from natural resins are difiicult and necessitate several operations on account of more or. less sourness of said resins.

According to the present invention, my process consists in dissolving artificial cumaron resin 1n benzln, ga'solene or benzol orin mixtures of thesesolvents. ll may also usechlorethylene as a solvent, either alone or mixed with one or more of the solvents mentioned above.
